We may get some benefit form considering other standardisation activity in this 
domain?  

RFC3986 defines the generic syntax for the Universal Resource Identifier (URI)
https://tools.ietf.org/html/rfc3986

As netCDF variables are resources that are being identified within the domain 
of a netCDF file, could we benefit from just adopting RFC3986?

This has a reserved character section:
https://tools.ietf.org/html/rfc3986#section-2.2

Disclaimer: I have not cross referenced this in detail with the NUG to examine 
consistency or problem areas (potential for contribution if useful)
First glance, these look pretty similar.

If these are consistent, then adopting the NUG definition unchanged looks 
sensible to me. It already mandates against the use of a '/' character, which 
is the most problematic one for me, given groups and variable identity within 
groups.

I'd like to see an explicit reference to the relevant NUG section in the text 
or linked, as I had to search a bit and I know what I'm looking for
I think:
https://www.unidata.ucar.edu/software/netcdf/docs/netcdf_data_set_components.html#Permitted
is stable enough for a standards document 
(@ethanrd do you agree this is a stable URI for the resource please?)
